Induction vs Coal: forging a hardy tool

Forging two "wedging" hardies (Brian Brazeal style) from 1 1/4" square (about 32mm) stock. The first using induction. The other using coal. I discuss pros and cons of each method. TL;DW: induction is faster, unless you already have the coal forge going at full heat, and produces a cleaner forging. Generally, the coal forge has significantly more heat output and is more accommodating of different shapes. However, it takes a significant time from first lighting the fire to get to full heat and also contaminates the work with "clinker" impurities that cause pitting unless fastidiously brushed off before forging (thus wasting the hottest and most production part of the heat).
